How much ATP can be obtained by the cell from the complete oxidation of one glucose...
In glycolysis, one glucose molecule yields pyruvates, ATP and NADH. Depending on the system used to shuttle the electrons from NADH into mitochondria, these NADH become NADH or FADH2. Converting the pyruvate(s) into acetyl-CoA's produces 2 NADH. One pyruvate/Two pyruvates pass(es) through the citric acid cycle starting with acetyl-CoA produces GTP, FADH2, and NADH. In the electron transport chain, each FADH2 generates ATP and each NADH ATP.
Which of the following is not a net product of the citric acid cycle for each molecule of pyruvate generated in glycolysis? Select one: a. 1 ATP (GTP) b. 1 acetyl coA c. 3 NADH d. 1 FADH2 Question 2 Which of the following is NOT an end product for an acetyl group that enters the citric acid cycle? Select one: a. ATP b. NADH c. FADH2 d. oxaloacetate Question 3 Once they have been processed through the citric acid...
Question 5 1 pts What is the main purpose of the Kreb's cycle (also known as the TCA or Citric Acid cycle) To produce ATP from the energy stored in acetyl-CoA To oxidize pyruvate and produce NAD and FADH2 To recycle NADH for use back in glycolysis To produce carbon dioxide by the reduction of pyruvate To produce NADH/FADH2 from the oxidation of acetyl-CoA

A) 2 ATP molecules B) 5 ATP molecules C) 12 ATP molecules D) 20 ATP molecules E) 32 ATP molecules
In Glycolysis the first five reactions involve: Oxidation of acetyl CoA Oxidation of pyruvate Release of energy Preparation of glucose to be split. NAD+ is regenerated by: ATP synthase Lactate dehydrogenase Rubisco Under aerobic conditions pyruvate:
Which one of the following statements about glucose metabolism is correct? A. Prokaryotes do not perform Krebs cycle for respiration. B. Krebs cycle involves the breakdown of a molecule of pyruvate into 6 CO2, 8 NADH, 2 FADH2, and 2 GTP molecules. C. The enzyme that catalyzes the addition of phosphate molecules to ADP in order to make ATP is called a kinase. D. In both glycolysis and Krebs cycle, the energy released from the breakdown of molecules is being...
